Be it known'that 1, JAMES J COOPER, -residing at 915 Olive street, St. Louis, Mis-l souri, and being a citizenof the4 United States, haveinventedf certain new and "us'e ful Improvements in Floor-Beams, of which the following is a full, clear, and exact description, such as will enable others skilledv in the art to which it appertains to makev and'tofujsey the same, reference being had to the accompanyingl drawings, which illustrate the preferred form of the invention, though it `is to be understood that the invention is not limited to the exactl details of construction shown and described, as it is obvious thatv various modifications there# VVof will occur to persons skilled in the art.

lIn saiddrawings: Figure 1 is a planfview of a fragment of a car underframe equipped with the invention herein described.' Fig. 2 is a transversefvertical sectionalvieii'i taken v ony the line 2-2 of Fig. 1, looking in the hereinafter described.

direction indicated by the arrows. Fig. 3 is a vertical longitudinal sectional view taken on the line 8 3 of Fig., 2. Fig. k4: is

Van elevational view of a fragmentary portion of the center lsill shown. atlthe right in Figs 1 and 2, Ashowing''perfora'tions for the transverse members vwhich are projected therethrough, ashereinafter described. Fig. 5 is an elevational viewof a similar fragment of the center sill shown at the leftV of Figs. 1 and2. Fig. 6 is a sectional-,view similar to Fig. 2, showing a' slightly modi fied form of construction and' arrangement ofA parts, and Fig. 7 is a furthenmodification This invention is an 4improvement upon the construction shown in Keithley Patent 707 ,7 02,'and is designedV to permit the use of pressed cross bearers or transoms, as they are called in said Keithley patent, which may' be of any depth outside ofthe center sills;

that is, between the center sills and side sills,V

and 'which may be ysupported by the center sills so that the principal partof the'load to be carriedby the car underframe' will be transmitted to the center sills,"-as in said Keithley patent.

T6 obviate cutting largeopeiiings in the center sills for the passage of continuous cross bearers through thespaced center sills is one of the objects ofthe invention and to permit the removal of one cantaliver portion of the cross bearer of the present in- Y n SpecificationiofrLetters ;y vlgmiigelpltie-(l Appiicatign iiiedsepti'nbe; 16,1913. fs-eriaiii.' 799,001.

vention ,Without the necessaryy removalof the other or companion portion, `is another object. u Q' f f v'The invention is shownin the drawings as comprising a cross bearer, which ,derives its support from the center sills and projectsv transversely thereof outwardlyy below sidesills, 1 which are mounted upon 3and` aiiixed to the outer lends of kthe cantaliver portions Ofthe'cross bearer. Referring specifically to the parts: A-A refer to thes'pacedf-center sillv parts, which comprise vertical webs' perforated, -as vhereinafter described, withtop and bottom reinforcing langles -B'-C, respectively, and a top cover-plate D secured to the top angles B," though -it' is to be lunderstood while I have illustrated a conventional form `of plate gir-der center sill united by top'covei plate, Ifdo not wish to `be limited toA any specific form of center sill construction, las rolled sections spaced apart or a single" rolled section comprisinga singlev centerA sill may be employed Within: the spirit of the presentjinvention. l. v f f Coperating with the center sill thus referredjto, I employ a transverse '-member, which may be a cross bearer orftransom intermediate the'bolsters of a car underframe,

orthe construction may be used 'atfand for Figs. 1 and 2 `consists of two presseddia.

The diaphragms '7 and 7a may-beef form outsidel of` the center sills and .may be of y uniform' depth from the center sills to their outerv ends, or may be of increasing depth from their outer ends toward the center sills,ifdesired,-for example, as shown in vFig. 7. The diaphragms 7F are deeper at v their inner ends; that is, the portion nearr iio 85. the bolster ofsuchiinderframe, and where riveting?k areaf between f. th'eai diaphnagrrissl 7'? and the-center sills. Where, liewever-,- it is 'preferred to use diaphragms or cross bearfy ing members Which are of uniform dptl outside of the center sills, I prefer to employ angle; connectiom'plates'l 10 of""'relatively' large area, which are,securedbyyrivetsa1L to the Webs of the center sills and by rivets 12 to the Webs of said diaphragme; ini iaddif tion .to .which I, prefer. ,toy yemploy '-.topand' bottom tie vplates 13V and" 14, respectively, which tie plates pass, throughy slats@A l5* i and 16 cutfin'thc Webs oif'sthe;cen-iter".,sills-,1`
